Description

COMPOSITION AND ITS USE IN PAPER MANUFACTURE The invention relates to a composition used to improve softness in paper products. The invention also relates to a papermaking process in which the composition is added to the cellulosic suspension or applied to a wet or dry paper web. The composition comprises an oil, wax or fat; at least one cationic, amphoteric or non-ionic polymer; and a compound selected from anionic surfactants and anionic microparticles; and one or more nonionic surfactants. Background

[0002] Wefts or sheets of paper, usually called thin paper or thin paper wefts, are commonly used in paper towels, napkins and thin facial paper and toilet paper. The important characteristics for these papers are softness, absorbency and strength. There is a work in progress to improve each of these characteristics without seriously affecting the others. Conventionally the thin pressed paper and methods for making such paper are well known in the art. Said paper is typically made by draining and forming a cellulosic suspension in a wire. The suspension cellulosic is usually contained in the upper box before being deposited in a Fourdrinier wire to form a paper web. The paper web is then typically vacuum dehydrated by vacuum dewatering and further dried by pressing operations wherein the web is subjected to pressure developed by opposed mechanical members, for example cylindrical rollers or an extended grip press. The dehydrated web is then pressed and dried by a steam drum apparatus known in the art as a Yankee cylinder. Conventional fluff and methods for making such paper are well known in the art. Said paper is typically made by making a sheet of paper in a Fourdrinier wire and subsequently pressing and drying the paper sheet in bales or rolls. The dry paper is then defibrated using a hammer mill or a pin defibrator to form a fluff. The typical products made of fluff are diapers and feminine hygiene products. The fluff can also be used to produce paper products laid in the air. The softness is a tactile sensation perceived by the consumer that holds a particular product, rubbing it through the skin or rubbing it inside the hand. The Softness of a sheet can be achieved by mechanical means.

For example, the sheet can be calendered to flatten the ridges formed when the sheet is pleated. The sheet can also be treated frictionally in order to eliminate any hardness. However, these approaches are often insufficient. One way to make paper softer is to add a softening compound to the cellulose suspension. The softening compound interferes with the natural fiber to fiber bond that occurs during sheet formation in papermaking processes. This reduction in bonding leads to a softer, or less rough, sheet of paper. WO 98/07927 describes the production of soft absorbent paper products using a softener. The softener comprises a quaternary ammonium surfactant, a nonionic surfactant as well as strength additives. The softening agent is added to the cellulosic suspension before the paper web is formed. A softening compound can also be applied to a dry or wet paper web, eg, by spraying. If the paper web is dry, the softener compound can also be printed on paper.

US 5,389,204 discloses a process for making soft thin paper with functional polysiloxane softener. The softener comprises a functional polysiloxane, an emulsifying surfactant and surfactants that are non-cationic. The softener is transferred to the dry paper web through a heater transfer surface. The softener is then pressed on the dry paper web. WO 97/30217 describes a composition used as a lotion to increase the softness of absorbent paper. The composition comprises an emollient which is preferably a fatty alcohol or a waxy ester. The composition also comprises a quaternary ammonium surfactant as well as one or more nonionic or amphoteric emulsifiers. Most softening compounds, whether added to the cellulose suspension or applied to the paper web, contain quaternary ammonium surfactants. Since producers and consumers experience increasing environmental importance, quaternary ammonium surfactants are not always accepted. Quaternary ammonium surfactants are generally toxic to aquatic organisms and are generally considered undesirable chemicals.

An object of the invention is to provide a composition for improving the softness of a paper product. A further object of the invention is to provide a composition substantially free of quaternary ammonium surfactants. Still another object of the invention is to provide a single composition suitable for addition to the cellulosic suspension and applied to a wet or dry paper web, instead of several different compositions as described in the above branch. Still a further object of the invention is to provide a composition which has a high tolerance towards the anionic transfer of preceding production steps. Conventional formulations in this manner can be neutralized at the wet end when small amounts of harmful substances are released from the preceding production steps. It is also an object of the invention to provide a composition which, when added to the cellulosic suspension, will impart low bursting resistance, high wetting rate as well as low defibration energy to the paper to be produced. It is also a further object of the invention providing a composition which, when added to the cellulosic suspension, will impart a low knot content to the product. The Invention The invention relates to a composition used to improve softness in paper products, preferably products prepared from thin paper or fluff.

The composition can be applied in various stages in the papermaking process. The composition, for example, can be added at the wet end to the cellulosic suspension. A composition added to the cellulosic suspension to improve the softness of the product is called a detacher. The composition can also be applied to the paper web to improve the surface feel of the product, e.g., the softness. If the composition is applied to the wet paper web, the composition is called a softener. If the composition is applied to a dry paper web, the composition is called a lotion. The composition of the invention comprises (i) an oil, fat or wax (ii) at least one nonionic surfactant (iii) at least one anionic compound selected from anionic icroparticles and anionic surfactants (iv) at least one polymer that is cationic, nonionic or amphoteric wherein the nonionic surfactant is added in an amount of about 60 to about 1000 parts by weight per 100 parts by weight of the polymer. According to one embodiment, the composition is substantially free of quaternary ammonium surfactants. By "substantially free" is meant that less than 5% by weight of the composition is comprised of quaternary ammonium surfactants, such as less than 1% by weight, or less than 0.5% by weight. Any oil, grease or wax, which functions as an emollient, can be used in accordance with the invention.

The colloidal silica particles according to the invention can be modified and can contain other elements such as amines, aluminum and / or boron, which may be present in the particles and / or the continuous phase. Boron-modified silica sols are described, e.g., in US 2,630,410. The aluminum-modified silica particles appropriately have an A1203 content of from about 0.05 to about 3% by weight, such as from about 0.1 to about 2% by weight. The process for preparing an aluminum modified silica sol is further described e.g., in "The Chemistry of Silica," by Iler, K. Ralph, pages 407-409, John Wiley & Sons (1979) and US 5 368 833. The colloidal silica particles appropriately have an average particle diameter ranging from about 2 to about 150, such as from about 3 to about 50, or about 5. around 40 nm. Suitably, the colloidal silica particles have a specific surface area of from about 20 to about 1500, such as from about 50 to about 900, or from about 70 to about 600 m2 / g.

According to embodiment, the anionic compound is an anionic surfactant. The nonionic surfactants which can be used according to the invention generally include ethoxylated or propoxylated fatty acids or fatty alcohols. Ethoxylated fatty acids and fatty alcohols have been preferably ethoxylated with from about 1 to about 30 ethylene oxide (EO), or from about 4 to about 25 EO. The ethoxylated fatty acids and fatty alcohols can have from about 6 to about 30 carbon atoms, or from about 6 to about 22 carbon atoms. The propoxylated fatty acids and fatty alcohols may have been propoxylated with from about 1 to about 30 propylene oxide (PO), or from about 1 to about 8 PO. The propoxylated fatty acids and fatty alcohols preferably have about 6 to about 30 carbon atoms, such as about 6 to about 22 carbon atoms.

It is also possible to use carbon dioxide instead of propylene oxide. The polymer is usually present in the composition in an amount of about 1 to about 50, such as from about 5 to about 40, or from about 10 to about 30% by weight based on the dry weight of the composition. The oil, fat or wax is usually present in the composition in an amount from about 1 to about 95, such as from about 30 to about 80, or from about 35 to about 75% by weight based on the dry weight of the composition. The anionic compound is suitably present in the composition in an amount from about 0.1 to about 10, such as from about 0.5 to about 4, or from about 0.6 to about 2% by weight based on the dry weight of the composition. According to one embodiment, the nonionic surfactant is present in an amount from about 70 to about 800, or from about 80 to about 600, or from about 100 to about 500, or from about 150 to about 400 parts by weight per 100 parts by weight of the polymer. The composition can be prepared by first mixing the oil, fat or wax together with the anionic and nonionic surfactants to provide a mixture of emollient-surfactant. The emollient-surfactant mixture can be heated to about 25 to about 70 ° C. An aqueous solution containing the polymer is properly prepared in which solution the polymer content constitutes from about 0.1 to about 50, e.g., from about 0.5 to about 25% by weight. The aqueous solution can be heated to about 25 to about 70 ° C. The emollient-surfactant mixture can then be emulsified in the aqueous solution containing the polymer by a static mixer, an ultra-turrax high shear device or a homogenizer. The product emulsion can then be cooled to room temperature. Cooling, for example, can be done using a heat exchanger. According to one embodiment, the mixture of emollient and surfactant is emulsified to the aqueous solution containing the polymer by means of a static mixer. The composition can be produced in advance and then delivered as a product to the paper mill. The composition can also be prepared on site in the paper mill of the different components. It is also possible to add additional components to the composition. To prevent deterioration of the composition, a preservative agent can be added. Various cosmetic additives may also be included, for example antioxidants, e.g., tocopherol, and aloe vera. The invention also relates to a process for the production of paper comprising adding the composition as described herein to a cellulosic suspension wherein the process further comprises draining the cellulosic suspension in a wire to form a paper web. According to one embodiment, the composition can be added in an amount from about 0.1 to about 15 kg / ton of dry cellulosic fibers. When the debonder is used to make the fluff, the composition is usually added to a cellulosic suspension in an amount of about 0.1 to about 15, such as from about 0.3 to about 10 kg / ton of dry cellulosic fibers. When the debonder is used to manufacture thin paper, the composition is usually added to a cellulosic suspension in an amount of about 0.1 to about 15, such as from about 0.5 to about 4 kg / ton of dry cellulosic fibers. When used as a debonder in this process, the composition, as already stated herein, is added to the cellulosic suspension before the paper web is formed. The use of detachers is very common when making borrilla and thin paper. The unloader will interfere with the natural fiber-to-fiber links so that the resistance is reduced. Reducing resistance, the softness of the fluff and the thin paper products is increased. According to one embodiment, the components of the composition can be added separately to the cellulosic suspension. Preferably, an emulsion of the oil, fat or wax and the anionic and nonionic surfactant can be added as a premix and a polymer, e.g., in an aqueous solution, can be added as a separate component to the cellulosic suspension. .

To evaluate the operation of the unloader, the bursting resistance, defibration energy and wetting regime can be measured. The low burst strength and low energy defibration shows that the fiber to fiber links are weak, which in turn facilitates the production of thin paper with improved smoothness. The wetting regime indicates that the finished product will have good absorption properties. Likewise, when using borrilla in airborne applications, it is important to minimize the number of knots. The knots can be described as bundles of fibers. A high number of knots can lead to low formation and running capacity in the process spread to the air. When the composition is applied to a wet or dry paper web, the surface touch can be improved. The superficial touch can be described as those superficial properties that are sensations tactiles perceived by the consumer. Superficial touch can be evaluated by gene in panel tests. Examples of said properties are softness, slip and uniformity.

According to one embodiment, the composition is added to the sheet as a single addition. According to another embodiment, the polymer can be added to the cellulosic suspension before the formation of the weft, while the oil, wax or fat; the anionic compound; and the nonionic surfactant are added to the wet or dry paper web. The invention also relates to a process for the production of paper which comprises applying the composition as described herein to a wet paper web. When the composition is used as a softener in the papermaking process, the composition is usually sprayed onto the wet paper web after the press section but before the Yankee cylinder. By using the composition as a softener, it is possible to obtain a paper with high surface smoothness and minimum resistance reduction. According to one embodiment, when the composition is used as a softener in the manufacture of thin paper, the composition is usually added in a amount from about 0.1 to about 10, preferably from about 0.3 to about 4 kg / ton of dry cellulosic fibers. The invention also relates to a process for the production of paper comprising applying the composition as described herein to a dry paper web. When the composition is used as a lotion in the above process, it is usually sprayed or printed onto the dry paper web. This is usually done in the conversion process in which the final thin paper product is formed. The lotion is properly present as drops on the wet surface of paper and is not bound to the fibers in the same way as a softener. The lotion modifies the surface properties of the thin paper, but the lotion is also added due to cosmetic reasons since the location can be released from the paper and transported to the consumer. According to one embodiment, the dry paper web has a dry content of at least about 50, such as at least about 65, or at least about 80% by weight. In accordance with one modality, when the The composition is used as a lotion to make thin paper, the composition is usually added in the amount of from about 0.1 to about 70, such as around 5 to about 50 kg / ton of dry cellulose fibers. The cellulosic fibers used by the present invention will typically include fibers derived from wood pulp, which includes chemical pulp such as Kraft, sulphite and sulphate pulps, as well as mechanical pulps such as ground wood, thermomechanical pulp and thermomechanical pulp modified with chemicals. Recycled fibers can also be used. The recycled fibers can contain all the pulps mentioned above as well as fillings, printing inks, etc. Chemical pulps, however, are preferred since they impart a superior softness to thin paper sheets made therefrom. The use of recycled fibers to make frequent thin paper includes a process step known as de-inking to remove as much as possible the printing ink from the fiber suspension and most of the filler material to obtain an acceptable brightness and operating capacity. of recycled fiber suspension paper machine. The deinking process often includes the addition of anionic substances such as saponified fatty acids and glass of water to the fiber suspension. These substances are sometimes taken to the paper machine and since these substances are anionic they can inactivate the cationic chemicals added to the material. These substances are called harmful anionic substances or "anionic garbage". According to one embodiment, additional components can be added to the cellulosic suspension used to make thin paper or fluff. These additives can be for example wet strength agents, dry strength agents, and wetting agents as well as other components usually used in the production process. According to one embodiment, an additional polymer that is either cationic, non-ionic or amphoteric can be added to the cellulosic suspension. Suitably the polymer is either a natural polymer, for example starch, or a synthetic polymer. According to one embodiment, an anionic polymer is added to the cellulosic suspension, these anionic polymers can include anionic per step growth polymers, chain growth polymers, polysaccharides, naturally occurring aromatic polymers and modifications thereof. The invention is further illustrated by the following examples, but the invention is not intended to be limited thereto.
